According to my small amount of research,
the Golden Mean has its roots in Ancient Greece and is still
used in today's design as an aesthetically pleasing method of dividing
space. It's said that these proportions can be seen everywhere in nature.

As I understand the Golden Mean,
the rectangle of specific proportions is broken up into three basic sections,
then the smaller of these sections broken into three sections, and so on.
A section created this way is sometimes called a Golden Section
or Devine Section.

To arrive at the rectangle's shortest
measurement, the longest measurement is multiplied by 0.618.

The longest measurement of the rectangle
is then multiplied by 0.618 and a division made at that point. This
creates two unequal sections. The longest measurement of the smaller section
is then multiplied by 0.618 and a division made. This adds a third
section and completes the basic Golden Mean proportions.

In the illustration above, these
steps were repeated until the sections were too small to divide further.
Once the sections were established, I drew a curved line beginning at the
lower left corner, and intersecting with the upper right corner of the
largest section, then with the lower right corner of the next smaller section,
and so on, following this curve until the line ended at the smallest section.

For anyone who's interested, this
is a mathematicians dream, or so it would seem from reading some of the
websites devoted to studying the Golden Mean. A search for "Golden
